DESCRIPTIONFor the NVMe device given, sends the WDC vendor unique crash dump request and saves the result to file​. In current implementation crash dump is captured if it is present​. On success it will save the dump in file with appropriate suffix​. Note that this command will clear the available dump from the device on success​. The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0)​. This will only work on WDC devices supporting this feature​. Results for any other device are undefined​.

OPTIONS−o <FILE>, −−output−file=<FILE> Output file; defaults to device serial number followed by "crash_dump" suffix

EXAMPLES•  Gets the crash dump from the device and saves to default file in current directory (e​.g​. STM00019F3F9crash_dump​.bin): # nvme wdc get−crash−dump /dev/nvme0•  Gets the crash dump from the device and saves to defined file in current directory (e​.g​. testSTM00019F3F9crash_dump​.bin): # nvme wdc get−crash−dump /dev/nvme0 −o test•  Gets the crash dump from the device and saves to defined file with pathname (e​.g​. /tmp/testSTM00019F3F9crash_dump​.bin): # nvme wdc get−crash−dump /dev/nvme0 −o /tmp/test
